أ) Causes low oxygen levels, barrel chest, and use of accessory muscles
Here's the breakdown of how structural damage in emphysema relates to the symptoms:
* **Structural Damage in Emphysema:** Emphysema involves the destruction of the alveoli (air sacs) in the lungs. This damage leads to:
* Loss of lung elasticity: The lungs become less able to recoil and push air out.
* Air trapping: Air gets trapped in the lungs because the airways collapse more easily during exhalation.
* Reduced surface area for gas exchange: With fewer and larger alveoli, there's less area for oxygen to enter the bloodstream and carbon dioxide to leave.
* **Relationship to Symptoms:**
* **Low oxygen levels (hypoxemia):** The reduced surface area for gas exchange makes it harder for oxygen to get into the blood, leading to low oxygen levels.
* **Barrel chest:** The chronic air trapping causes the chest to expand and become rounded like a barrel.
* **Use of accessory muscles:** Because of the difficulty exhaling and the reduced efficiency of the diaphragm, people with emphysema often have to use muscles in their neck, shoulders, and chest to help them breathe. This leads to noticeable movements during breathing.
* **Why other options are wrong:**
* **Improves breathing efficiency:** Emphysema *decreases* breathing efficiency due to lung damage.
* **Increases appetite:** Emphysema doesn't directly cause an increase in appetite. In fact, some people with emphysema may experience a decreased appetite due to the effort of breathing or other complications.
**Therefore, the correct answer is A) Causes low oxygen levels, barrel chest, and use of accessory muscles.**
